Weight in air = 2.1N
Relative Density = 8.4 (Here, Relative Density = RD)
RD = Weight of body in air / Upthrust
Relative Density = 8.4 (Here, Relative Density = RD)
RD = Weight of body in air / Upthrust
Therefore, Upthrust = Weight of body in air / RD = 2.1 / 8.4 = 0.25
Therefore, Weight of the body in water = 2.1 – 0.25 = 1.85N
